Jlhis invention reiams to improvements in whole at22. I This spring plank is proviiieci on railway car truck construction 'and aims with; a plurnlity of integral extensions 24 partic'iilarly to provide a truck having a rvl'uch are adapted to term a safety support spring plank carrying improved safety incasc the brake beams 26 drop because of means for the brake beam. In the trucks failure of the brake beam hangers 28 or heretofore used, it has been almost universal o her part of the brake rigging. In the W practice to form the brake beam safety snpbrake rigging illustreted the beams carry opports of separate pieces such as angle bars crating levers 30 which are connected to one or flnt hairs riveted or bolted to the spring another by a bottom rod/32. My improved plank, Due to vibration and weaving of spring plank is also provided with safety the trucks, it is practically impossible to supports 34 which are aoapted to prevent keep the prior forms of safety supports sethis hot onr rod. from fall ng shonicl anyof cnrely fastened in place.

In the embotln struction overcomes these (liiiicnltios and furment of the invention illustrated in Figs. 1 that possesses other advantages which \rill to J-i'inclusive, the safety supports 3% are he apparent from the iollowing specification iorincd by providing downwardly bent en- 70 when read in connection with the nccomtensions or wells 36 which are apertureel at pen'ying drawings. in the drawings- 37 to permit the hottoin IOil 32 to pass there' Fig. 11's a plan thereof with parts broken tl1rough Each weh 36 is bent at right anaway i th i t t f l -11 s; glcs to tor-n1 shc1f-hke supports 34:.

fications and substitntionnt' eqniwalcrnj. my be made by those skilicd'in the art without departing from the invention as defined in the appended claims c What- I claim is 1. A car truck including; spaced side fraunes, a pressed metal springplnnk tending transversely between suitl' trainee and brake beam safety supports pressed in tegzrally'with said-spring plank.

2. A car truck including spaced side frames, :1 pressed metal spring plank extending trunsyersely between said frames, brake beanie carrying levers by a bottom rod, and safety supports for said rmt pressed integrally with said spring plank.

annexes 3. The car truck of claim 2 with the addi ticnal feature (if integrally pressed brake beam supports.

4:, A car truck including spaced side frames, 2; pressed metal spring plank extending transversely between said frames, a brake beam carrying a lever connected to a bottom rod said spring plank having (lawnwarclly pressed flanges apertured to accbnr iuodate said-bettom rmi.

A car truck including spaced side frames, a pressed-metal'spring plank extentt ing transversely between said frames and brake beam snfetycsnpnorts pressed into grally 0n bntlrnides of said spring plank.

15. A car truck including a brake beam, and having a spring plank pressed from a sheet of metal with integral extensions'of suiiicient length to extend under said brake beams.

in witness whereof, I have hereunto signed my name.
